Banded iron formation

A typical banded iron formation consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe 3 O 4) or hematite (Fe 2 O 3), alternating with bands of ironpoor chert, often red in color, of similar thickness. A single banded iron formation can be up to several hundred meters in thickness and extend laterally for ...

In the south eastern exposures of the C Member a barite horizon is developed at the stratigraphic level of the banded magnetitehematite quartzite of the C1 Bed. Barite occurs as intercalated lenticular bodies in some places, and in others as persistent massive layers of 1 to m in thickness, oriented parallel to the regional banding.
